摘要： An implantable medical device for detecting and treating an arrhythmia includes an optical sensor adapted for positioning adjacent to a blood-perfused tissue volume. In one embodiment for controlling arrhythmia therapies delivered by the device, the optical sensor is controlled to emit light in response to detecting an arrhythmia, detect light scattered by the volume of blood perfused tissue including measuring an optical sensor output signal corresponding to the intensity of scattered light for at least four spaced-apart wavelengths, and compute a volume-independent measure of tissue oxygen saturation from the detected light. The hemodynamic status of the arrhythmia is detected in response to the measure of tissue oxygen saturation.

摘要： A medical system that includes an identification patch having a memory that stores identification information associated with the patch. A monitoring device to be used with the identification patch interrogates the patch to obtain the identification information stored within the memory of the patch. The monitoring device determines whether the identification information is valid and, if so, measures values representing one or more parameters of the patient. If the identification information is not valid, monitoring device does not measure values representing the one or more parameters of the patient.
